Lithium Ion Battery Fuses and Switches
Whether powering a smartphone or an electric bike, protecting Li-ion battery packs from overcurrent and overcharging is key to safety and reliability. SEFUSE® battery fuses and SEREB® thermal battery protection switches are used to protect Li-ion battery packs. SEFUSE® battery fuses include D6S type and S type, which protect Li-ion batteries from overcurrent and overcharging. The S type is a lead-free* product that reduces environmental impact. SEREB® battery protectors prevent overheating and overcurrent.
Compact, space-saving designs
The compact, space-saving designs of SCHOTT’s battery protection components make them ideal for applications with limited space. Surface-mount battery fuses come in ultra-thin profiles as slim as 0.85 mmm, and thermal protection switches are crafted from lightweight materials to reduce footprint.
A wealth of experience in reliable electronics protection
SCHOTT has a strong reputation as a specialist in electronics protection. Leveraging our expertise with SEFUSE® thermal links, which prevent electronics from catching fire due to overheating, we apply the same high-quality standards and extensive experience to develop and manufacture SEFUSE® battery fuses and SEREB® thermal battery protectors.
Extensive lineup of protectors for rechargeable batteries
SEFUSE® battery fuses are used as secondary protection in battery management systems (BMS). The SEFUSE® battery fuse line supports rated currents from 12 to 60A and is suitable for high-current applications, including rechargeable batteries for power tools. SCHOTT also offers a resettable SEREB® device that detects abnormal temperature rises in battery cells.
